This is a basic troubleshooting guide for users to try and find the cause of issues. Following the guide should allow you to hopefully fix the issue, or at least figure out the source that is causing it so that when posting on the forum users have more information available to offer help.
1 /Are you running the latest version of Maxthon?
Check the forum for any new releases and update/reinstall. Most issues will generally be resolved in new builds, or just by the reinstall process. Also ensure you have the latest version of Flash and any other plugins you might be using.
If an update/reinstall doesn't work, try doing a clean install which removes all userdata during the uninstall process. Your userdata will be restored if you are using a Maxthon Passport. If you're using a local/guest account, make sure you have a backup of your Maxthon userdata folder (Open an explorer window and type %appdata%\Maxthon5\Users\guest into the address bar). Keep a copy this folder, then copy it back once you have reinstalled.
2 /Do a forum search.
Chances are someone has had the issue before you and a fix has been found. If you find a solution that works, reply in the thread so others know that it has worked for other users as well.
3 /Try changing to Retro Mode.
A great feature of Maxthon that allows you to view a site using the Internet Explorer renderer in case the site has issues with Blink. Main Menu > Tools > Switch Browser Core, or press the lightning button on the right of the address bar so it changes to a blue e icon.
4 /Connection error?
(Eg. unable to resolve domain name or can't connect error) try with another browser to see if it also has the same issue. Use a site like http://isup.me to check that the site is in fact online. Also check there isn't a problem with your DNS servers. You can try testing with Google (8.8.8.8) or OpenDNS (208.67.222.220) servers.
And always provide a link to the site/page in question when posting so others can check to see if the problem is more widespread.
5 /Try disabling AdBlock Plus.
Sometimes overly aggressive blocking can cause issues on a site. If this fixes the problem some of your rules may need to be revised. Post on the forum and someone should be able to offer a solution.
6 /Try deleting/clearing cookies.
There might be a corrupt or invalid cookie causing the problem. Deleting them will ensure new ones are created.
Option 1: (Ctrl-Shift-Del) or from the Main Menu > Clear Browsing Data menu option, or toolbar. [Images here]
Option 2: To delete cookies for only one site you can use the Developer Tools. [Images here]
Option 3: You can also use the following 3rd party programs: -CookieSpy#1 which can show Maxthon cookies, and DB Browser for SQLite which offer more advanced means of working with cookies. [More details here]NOTE: Only option 1 is recommended. Options 2 & 3 are only for advanced users.
7 /Try disabling all extensions.
If disabling extensions fixes the problem then one of your extensions is causing the problem. Enable them one by one testing after each until you find the one causing the problem.
8 /Check the advanced options.
Ensure you are using the default User Agent (should be unchecked), check with GPU acceleration on/off, and ensure that "Allow all sites to run plug-ins is enabled" if trying to troubleshoot a plugin related problem. These can be found by going to Main Menu > Settings > Advanced.
If the above steps don't resolve the issue, follow the next steps which should help determine if the problem is with Maxthon, your account settings or system related and hopefully lead to the cause of the problem.
9 /Sign out of your Maxthon Passport.
Check to see if the same problem still occurs. If not signing in fixes the problem, then it's more than likely a settings related issue. Disable all sync options from the menu then enable them one by one, testing for the problem until it occurs again. Once you know which settings are causing the issue make a post on the forum with the details for further assistance.
10 /Test with Maxthon Portable. Download & extract to any folder, run, check for the issue. DO NOT SIGN IN to your Maxthon Passport account. If this works then it's more than likely related to your install. Doing a clean install should fix the problem.
If going through the above doesn't fix the problem, then start a thread on the forum to see if someone can help out. Offer as much information as you can, especially the following:
- Any error messages;
- What version of Maxthon and operating system you are running;
- Any out of the ordinary programs (network related like firewalls, downloaders like Orbit, mouse or other hardware related utilities);
- What you have tried to fix/find out what the issue was. Otherwise people will offer solutions that you may have already done;
- And if applicable link some screenshots or video if it will make things easier for others to understand the problem.
The best case scenario is you will find and fix the issue without having to wait hours or days for a response on the forum. At minimum you will narrow in on the issue allowing others to offer a quicker and more appropriate response for the problem. And you may learn something as well :-)
Happy troubleshooting!

Maxthon comes with a version of Adobe Flash to ensure the browser is able to play all Flash content upon installation, although this version isn't always the most recent. This is to ensure that any issues related to new releases of Flash don't cause issues with Maxthon. You can force Maxthon to use the most current version of Flash by following the instructions below.
The most recent version of Adobe Flash is available from here: http://get.adobe.com/flash
The "Allow all sites to run plug-ins" option must be enabled in Settings > Advanced.
The MX Flash Updater is recommended to check and update your system and Maxthon Flash version.
The auto-updater tool created by Truuuc also automates the Flash install procedures below, along with some extra options for languages and other plugins.
NOTE: the update programs or the instructions below will NOT work for Windows XP/Server 2000/2003.
If you have any issues with the above, please follow the descriptions linked below.
For Maxthon 4.9.x and later follow the instructions in this post.
For Maxthon 4.4.x and earlier follow the instructions in this post.

Step 1. Sidebar addons
Step 2. Bookmarklets
Step 3. Scripts
Step 4. Toolbar menu
Step 5. Localization
Русский перевод
Original Russian guide
Most of extensions for Maxthon Browser is just sidebar extensions. It's very easy for develop. Very easy. If you have predesigned template, you can make new sidebar addon in a few minutes. Addons for sidebar have minimum of functions, but you need minimum of efforts to make it.
We have a lot of sidebar addons for Maxthon. We have many addons for the same websites (Facebook, Twitter, Google+ etc.) with different icons and size of windows. I'm perfectionist: I want to see beautiful icons and I want to have ability to resize the sidebar window. So I looked what is inside these extensions. I do not know anything about programming. This is just my experience.
Today we'll start learning how to make extensions for Maxthon. And we'll begin from simply addons for sidebar. Sidebar addons will be the basis for other our extensions. Are you ready? I want to show you how to make Google+ for MX sidebar. Why Google+? Because G+ was updated and now I use new desktop website for my extension, and if you like old mobile version of G+, you can make your own extension! Let's start!
NB: I will use old screenshots from original Russian guide for Yandex.Mail. Because Google+ is more relevant than Yandex.Mail now, but I'm too lazy to make new screenshots. And there is Russian on these screenshots. Sorry.
1. Create a new folder and name it Google Plus.
2. Inside Google Plus folder create a new folder and name it icons.
3. You have to make three icons in different sizes for your extension: icon_48.png, icon_32.png and icon_16.png (for Extension Center, sidebar and toolbar).
NB: .png is the format of image, not just a part of name. You can not just add .png in the file name, it will not work! You should use any program to change the image format (for example Paint.NET) or just search only PNG images (for example in Yandex).
4. If you don't have icon in PNG, you can make it from any other format. Just open your image in Paint or Paint.NET, click File → Save as... and choose .png in file type field.
5. Now we have icon for our addon and we need two copies. Copy and paste. Copy and paste.
6. Now we have to resize our icons. Right click on any file, choose Open in (I don't know how it's called in English versions of Windows) → Microsoft Office Picture Manager. In Picture Manager window click Edit Picture → Resize (or something like that). We need 48x48 (icon_48.png), 32x32 (icon_32.png) and 16x16 (icon_16.png).
7. Working with icons is completed, go back to the Google Plus folder.
8. File def.json have to be in the extension folder. So...
Open notebook, write information about you (as author) if you want: name, email, website. Usually I add source in "website" field. I think, your def.json will look like this:
[{
"author": "who developed it",
"name": "your name",
"email": "your email",
"website": "https://plus.google.com/"
In theory, users can see this information in Extensions Center, but... I never saw this.Add the date when you made it:
"date": "05.12.2015"
The next what you need to specify is type and version of your extension. You can use any number, but we start from v.1.0.0:
"type": "extension",
"frameworkVersion":"1.0.0",
"version":"1.0.0",
Maxthon uses GUID to indicate and update extensions. You can not upload your addon in Extension Center if someone used the same GUID. And you can nou use addons without any GUID. Where you can get it? Here. And it looks like this:
"guid": "{ABD3EBCE-FFD0-4D0A-A68A-B93E446310A3}",
Now we'll name your addon:
"name": "Google+",
"icon": "icon",
"title": {"en": "Google+"},
"description": {"en": "sidebar addon for Google+"}
Now you have to choose where you can see your addon. Most of MX extensions use button in sidebar and old MX users like this. But new users who came from Chrome want to see extensions in toolbar. Toolbar buttons look very funnily with Ultimate Chrome skin. So... sidebar or toolbar?
"actions": [{
"type": "panel",
"entryPoints": ["sidebar"],
Next point is ability to close the sidebar window. MX Team made strange choice: by default you can only minimize sidebar window, but not close. I have no idea why. So just add this:
"stopOnClose": true,
Enter address of page what you want to see in sidebar window. For mobile version of Google+ this is:
"main": "https://m.google.com/app/basic/",
What about the ability to pin and resize window? Use true if you need it and false if you don't:
"allowPin": true,
"resizable": true,
And finally, the last thing what you have to specify is windows size:
"width": {"default": 480,
"min": 300,
"max": 500},
"height": {"default": 720,
"min": 610,
"max": 1200}
That's all and now you need only close all brackets:
}]
}]
If you did all right, now you see some like this:
[{
"author": "who developed it",
"name": "your name",
"email": "your email",
"website": "https://plus.google.com/"
"date": "05.12.2015"
"type": "extension",
"frameworkVersion":"1.0.0",
"version":"1.0.0",
"guid": "{ABD3EBCE-FFD0-4D0A-A68A-B93E446310A3}",
"name": "Google+",
"icon": "icon",
"title": {"en": "Google+"},
"description": {"en": "sidebar addon for Google+"}
"actions": [{
"type": "panel",
"entryPoints": ["sidebar"],
"stopOnClose": true,
"main": "https://m.google.com/app/basic/",
"allowPin": true,
"resizable": true,
"width": {"default": 480,
"min": 300,
"max": 500},
"height": {"default": 720,
"min": 600,
"max": 1200}
}]
}]
9. Save this note as def.json: click File → Save as, in the file type field choose All files and write name for this file: def.json
10. All done! You need only pack it!
You need MXPocker for this. Just drag Google Plus folder in MXPocker and get you GooglePlus.mxaddon:
Use duble click to instill it in your browser. If duble click does not work or you use portable version, just copy new file in C:\Users\WINDOWS USER\AppData\Roaming\Maxthon3\Users\MAXTHON PASPORT\Addons and it will work!
Look up. You made the first your own extension for Maxthon. But... In new Opera you need only one extension to add any website in sidebar. In Vivaldi and Firefox you can just add website in sidebar by link like in bookmarks. And only Maxthon users must dance with tambourine every time! Why?
P.S. If your extension does not work, write me about this. I did not test this addon and maybe I made a few silly mistakes...

Recently, more and more websites detect ABP and prevent access to content if it is detected.
This eliminates the need for ABP, since one can access those pages only if ABP is disabled (or some tricks are done). Is there a way to prevent websites from detecting ABP?
The last thing I want is to disable it exactly where the ads are lurking...

HELLO GUYS , I KNOW MAXTHON WAS UPDATE THE FORUM , AND THEN HARD TO CHANGE SKINS , HOW CAN I CHANGE MY SKINS ? ANYONE KNOW ? HOW TO CHANGE IT ? PLIS GIVE ME SCREENSHOT OR ETC .. THAT CAN SHOW ME HOW TO CHANGE SKINS >
THANK YOUUUUUUUUUUUUUUUUUUUUUU !!!!!
